Biology organelles quiz

cell membrane

in all cells; it works as a barrier, lets things in and out, and keeps thing things in; made of phospholipid bilayer; its like the dry walls and the door

phospholipid bilayer

lets everything in the cell made of this be interchangeable

cell wall

found in plants, fungi, prokaryotic, and some protists; keeps in water; made of celllose in plants, and chitin in fungi; like the support beam

nucleus

found in eukaryotic cells, both animal and plant; where ribosomes are made; like the boss's office

chromatin (DNA)

found in all cells, only in nucleus in eukaryotic; is the information needed in a cell; made of nucleotides; like the instruction manual

nucleolus

found in eukaryotic cells; where ribosomes are made; like the machine maker (of ribosomes)

nuclear envelope

found in eukaryotic cells; surrounds the nucleus; has a double membrane; like the windows and walls in boss' office

microtubules

found in all cells; moves things around, maintains the shape of the cell, flagela and cilia are made of these; found all throughout the cell, are hollow tubes of protein tubes; like the conveyor belt

microfilaments

found in all cells; helps cells move, anchor things to the microtubles; made of protein threads, are everywhere in the cell; like nails, screws or duct tupe

cytoplasm

found in all cells; gell of the celll, all the stff (liquid and solid) in the cell exept nucleus; like the inside of the factory outside of boss's office

ribosomes

found in all cells; produces proteins according to the nucleus; made of RNA and protein, found everywhere; like the robot, small machine within the factory

rough endoplasmic reticulum

found in eukaryotic cells; centralized location for protein protection; a folded membrane covered in ribosomes, can make vesicles by pinching off a part; like the main factory workroom

smooth endoplasmic reticulum

found in eukaryotic cells; breaks down toxic chemicals, makes molecules that aren't protein; no ribosomes on it, located a lot in the liver, more tubular than Rough ER; like a drug inspector

golgi apparatus

found in plant and animal; modifies sorts and packages proteins and other materials from the ER, for storage or to go out of the cell; sack of closely opposed membrane ER; like the UPS system

lysosomes

found in eukaryotic cells, animal (not usually in plants); clean up crew, breaks down/digest small molecules; can be dangerous if it pops it wll kill the cell, can lead to Tay-sachs disease; like the recycle bin

vacuoles

found mostly in plant (some animal); store water, salts, protein, carbs; like the storage room in a factory

chloroplasts

found plant cells some algae; captures energy from sun and converts it to chemical energy (photosynthesis), makes glucose-sugar that mitochoria use; have their own DNA capsules; like solar panel

mitochondria

found in eukaryotic, plants and animals; converts chemical energy and food compounds into energy that can be used for the whole cell, turning sugar into burst of energy, cellular resparation; two layers of membrane, smooth outer membrane, folded inner mem

plasmodesmata

found eukaryotic cells in plants; connection between adjacent cells; like a sidewalk to the cells

desmosomes

found eukaryotic cells, animal; connection between adjacent cell; like a sidewalk to the cells

vesicles

found in eukaryotic cells; for transport of things; small membrane sack; like a cardboard box or envelope
